This PR adds support for improved fiction shows, AKA serial shows, that have season and episode information. For example "White Vault".
The changes done are inspired in this blog post: https://www.theend.fyi/article/unlocking-the-potential-of-fiction-podcasts-a-call-to-podcast-app-developers

It adds the following features:

• A new sort type, Serial, that orders the episode by ascending season number and episode number
• Episodes that don't have a Season and Episode number are group in section called Extras in the end of the list of episodes
• By default if a podcast is added and it has the showType == serial the default sort order for the episodes is set to Serial and Grouping by Season
• Adds a new button to support download of all episodes of a season.

Here are some videos of the feature:

This is still a proof of concept but would like feedback on the following:

• A better name for the sort type, Serial does not look like a obvious name
• Where to add the download section button, the header may not be the best option, we could also consider an option on Multiselect that allows to select a complete season, and then users press download on the options button?

To test

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.
